Most Mental Health Apps Are Built for Good Days

Calm tells you to breathe. Headspace gives you a 10-minute meditation. But what happens when you're at your lowest and the smiley-face mood picker feels like a joke?

I’m going to say something that might sound ungrateful considering I’m building a mental health app myself.

Most mental health apps are useless when you actually need them.

Not all of them. And not useless in the “this has no value” sense. Calm is a good product. Headspace is well-made. Finch is cute and people love it. I don’t have a problem with any of them individually.

My problem is with the entire category’s assumption about when you’ll use it.

The good-day bias

Open Calm when you’re feeling okay and it’s lovely. Soothing sounds, a gentle voice telling you to focus on your breathing, a little progress tracker that makes you feel like you’re doing something right. It works because you’re already in a state where calming down is possible.

Now open it when you’re in a genuine mental health crisis. When your mood has been tanking for three days and you don’t know why. When you haven’t slept properly in a week and the world feels like it’s made of glass. When you’re sitting in your car in a parking lot trying to decide if you can actually walk into the office today.

“Let’s begin with a deep breath.”

No. I need to understand what’s happening to me. I need to know if this is a pattern or a one-off. I need to figure out if my medication change two weeks ago is connected to this crash. I need something that treats me like an adult with a real condition, not a stressed-out person who needs a hug.

The smiley face problem

Almost every mood tracking app I’ve tried does the same thing. You open it, you pick a face — happy, sad, meh, angry — and you’re done. Maybe you write a little note. Maybe there’s a streak counter to keep you coming back.

And for mild stress and general wellbeing, fine. That works. But here’s the thing most of these apps don’t account for: when you’re genuinely struggling with a mood disorder, reducing your entire internal state to a smiley face isn’t just oversimplified. It’s kind of insulting.

There have been days where my mood was a 2 out of 10, my energy was actually a 7, my sleep was 4 hours, and my stability — the thing that tells me whether I can trust my own reactions — was near zero. Those four numbers tell a very different story from a sad face. They tell me I’m in a mixed state, probably sleep-deprived, potentially heading toward something worse. A sad face tells me nothing.

The problem isn’t that these apps are bad. It’s that they were designed by people optimizing for engagement metrics, not clinical utility. A smiley face picker has lower friction than a multi-axis mood entry. More people will complete it. The DAU numbers look better. The app store reviews are nicer.

But it doesn’t actually help you understand what’s going on.

What’s missing

Here’s what I’ve needed from a mental health app that I couldn’t find anywhere:

Pattern detection over time. Not “you’ve been sad for 3 days” but “your mood drops tend to follow sleep disruptions by about 48 hours, and the last two times this happened, here’s what preceded it.” That requires structured data, collected consistently, analyzed over weeks and months. Not a smiley face.

The ability to show my doctor something meaningful. I see my psychiatrist for maybe 15 minutes every few weeks. In that time I’m supposed to summarize how I’ve been doing, what’s changed, whether the medication is working. I’m doing this from memory, which is unreliable on a good day and completely useless when you’re in an episode. What I want is a report. Actual data. Here’s my mood trend, here’s my sleep, here are the flags. Let’s talk about the data instead of my vague recollection of last Tuesday.

Taking my condition seriously. I have bipolar disorder. That’s not “I’m feeling a bit stressed lately.” It’s a lifelong condition with medication, episodes, and real clinical consequences. The app I use for it should reflect that reality. It should know that a sudden spike in energy after a period of low mood might not be recovery — it might be the start of hypomania. It should understand that sleep disruption isn’t just “poor sleep hygiene.” It should be designed for someone whose mental health is a thing they manage, not a thing they optimize.

The market gap nobody talks about

There’s a weird gap in the market that I didn’t fully understand until I started building.

On one end you have the wellness apps. Calm, Headspace, Balance. Beautiful, well-funded, mass-market. Designed for people who are mostly fine and want to feel a bit better. Nothing wrong with that.

On the other end you have clinical tools. Apps your therapist might prescribe, or ones that integrate with electronic health records. Functional, often ugly, usually behind a clinician paywall. Not really designed for daily personal use.

In the middle — where someone with an actual diagnosis lives every day — there’s almost nothing. You’re too complex for the wellness apps and too independent for the clinical tools. You need something that’s built with clinical awareness but designed for daily life. Something that respects the severity of what you’re dealing with without making you feel like a patient every time you open it.

That’s the gap. That’s what I’m trying to build.

I’m not neutral about this

I should be honest: I’m not writing this as some objective industry analyst. I live with bipolar disorder. I’ve been the person in the parking lot. I’ve been the person staring at a smiley face picker thinking “none of these even come close.”

And I built Steadyline because I got tired of waiting for someone else to build it.

It’s not perfect. I’m still iterating on it, still learning what works and what doesn’t. But the core idea — that a mental health app should actually be useful on your worst days, not just your okay ones — that’s non-negotiable for me.

If you’ve ever opened a wellness app during a rough patch and felt like it was made for someone else, you’re not being ungrateful. You’re right. It was made for someone else.

Maybe it’s time we had something that was made for us.

I’m a software engineer who lives with bipolar disorder. I’m building Steadyline — a mood and mental health tracking app designed for people who actually need it. Not another meditation timer.
